Television viewers across the nation were updated about a missing Iowa news anchor who vanished more than 20 years ago.

New information from Mason City police and a look into some past suspects in Jodi Huisentruit's disappearance were the most noteworthy developments as CBS's "48 Hours" took a look at the case Saturday night.

Huisentruit was a 27-year-old anchor at KIMT-TV, a CBS affiliate in Mason City, on June 27, 1995, when she failed to show up for work to anchor the 6 a.m. broadcast. She hasn't been seen since.

"48 Hours" debuted never-before-seen footage of John Vansice, a friend of Huisentruit's who may have been the last person to see her before she vanished. Vansice, aged 20 years older than Huisentruit and believed to have had an infatuation with her, was questioned by authorities but never charged in the case.

Jeff Brinkley, Mason City's fourth police chief since Huisentruit's disappearance, said the search did not reveal any useful information. He would not comment on whether Vansice is still a suspect.

Brinkley, who has been with the department since 2016, admitted that evidence at the crime scene could have been lost because the scene wasn't properly processed. Huisentruit's hair dryer, keys and shoes were found near her car outside her apartment the morning she went missing. A palm print was on the car as well and there were signs of a struggle.

A friend of Huisentruit's said on camera that the scene was not immediately taped off and she had always questioned how well investigators handled the initial call.

Brinkley, though, seemed optimistic about how the investigation was going.

"I think that we're very close," the former Ames police lieutenant said of a break in the case. "I don't think it's (coming) fast." He did not say what other evidence police were reviewing besides the items found outside her apartment building.

Many viewers were introduced for the first time to another potential suspect, Tony Jackson. Jackson, who is serving prison time after being convicted of a string of Minnesota rapes in the 1990s, lived in Mason City near the time the blonde news anchor was last seen.

A few years following Huisentruit's disappearance, Mason City police said Jackson was not a "viable suspect" after interviews and further investigation.

Jackson declined an on-camera interview but defended his "integrity" in an email to the show. Brinkley would not comment on whether he is still a suspect.

Mason City police continue to investigate as do former journalists and detectives who use the website FindJodi.com.
